Chantdiscography.com offers a relational database of Western Plainchant on sound recordings. (The term “record” is used here to describe any sound carrier, including but not limited to shellac 78s, vinyl 45s, vinyl LPs, cassette tapes and compact discs.) It is a revision and expansion of A Gregorian Chant Discography, published in 1990. Data entry began in February 2010 and public access has been offered since November 2010. The
entry of known records issued since 1990 was the first priority, followed by the entry of records listed in the 1990
book. Both are complete, and new issues and records newly
discovered are still being entered.

Each chant is identified by one or more editions. The first page number identifies the edition heard on the record. The following page numbers identify editions that may be the same editions or different variant versions of the same chant. For
example, most hymns found in LH, AM and LU vary in text or melody or
both; the doxology or final strophe is usually a different text in
each of the three editions. A chant sung from none of the editions
listed is noted as a variant manuscript or variant edition with the
source cited if known. Chants that are not found in any modern liturgical edition may be identified from one
of various sources identified in the list of abbreviations. Some chants have not been found in any available source.

A
large number of previously unknown recordings has been lent to the
compiler for analysis by Manuel Alberto Díaz-Blanco González-Mohíno
of Belfort, France. Since 2015, a large number of analogue recordings never issued on CD have been digitized by Dominique Crochu and placed on the website of Musique Médiévale: http://gregorian-chant.ning.com Each digitized record can be accessed individually by copying the link in the comment box and pasting it into a web browser. Then each chant can be downloaded individually. You need to register on the website, but registration is free.

In this database, each
record is identified by format and country of origin. The format
codes are CD (compact disc), LP (12-inch or 10-inch vinyl long
playing record), MC (tape cassette), 33 (seven-inch 33rpm vinyl
disc), 45 (seven-inch 45rpm vinyl disc), 78 (78rpm shellac disc), and
DV (DVD video disc). The country of origin codes are the two-letter
internet country codes, including US and UK.

Since October 2013, a few entries have been added for information. The Maredsous set on Semen c.1933 is mentioned without contents. The lost Pathé cylinders (CY) of 1899 are mentioned. A
Parlophone set of hymns of 1927 is mentioned because it has been
erroneously catalogued in GSERM and WERM as chant. These are exceptions to the usual
criterion of confirmed data entry.
